	help
	  Enable MCUX Ethernet driver.  Note, this driver performs one shot PHY
	  setup.  There is no support for PHY disconnect, reconnect or
	  configuration change.

config ETH_MCUX_USE_DTCM_FOR_DMA_BUFFER
	bool "Use DTCM for hardware DMA buffers"
	default y
	help
	  Place the hardware DMA buffers into DTCM for better networking
	  performance

config ETH_MCUX_PROMISCUOUS_MODE
	bool "Promiscuous mode"
	help
	  Place the Ethernet receiver in promiscuous mode. This may be useful
	  for debugging and not needed for normal work.

config ETH_MCUX_RMII_EXT_CLK
	bool "RMII clock from external sources"
	help
	  Setting this option will configure MCUX clock block to feed RMII
	  reference clock from external source (ENET_1588_CLKIN)

config ETH_MCUX_NO_PHY_SMI
	bool "Do not use SMI for PHY communication"
	help
	  Some PHY devices, with DSA capabilities do not use SMI for
	  communication with MAC ENET controller. Other busses - like SPI
	  or I2C are used instead.

config ETH_MCUX_PHY_TICK_MS
	int "PHY poll period (ms)"
	default 1000
	range 100 30000
	help
	  Set the PHY status polling period.

config ETH_MCUX_PHY_EXTRA_DEBUG
	bool "Additional detailed PHY debug"
	help
	  Enable additional PHY related debug information related to
	  PHY status polling.

config ETH_MCUX_RX_BUFFERS
	int "Number of MCUX RX buffers"
	default 6
	range 6 16
	help
	  Set the number of RX buffers provided to the MCUX driver.

config ETH_MCUX_PHY_RESET
	bool "Reset the PHY at boot"
	help
	  Reset the ethernet PHY at boot. Requires dts properties int-gpios and
	  reset-gpios to be present.

config ETH_MCUX_TX_BUFFERS
	int "Number of MCUX TX buffers"
	default 1
	range 1 16
	help
	  Set the number of TX buffers provided to the MCUX driver.

config ETH_MCUX_HW_ACCELERATION
	bool "Hardware acceleration"
	help
	  Enable hardware acceleration for the following:
	  - IPv4, UDP and TCP checksum (both Rx and Tx)

config PTP_CLOCK_MCUX
	bool "MCUX PTP clock driver support"
	default y
	depends on PTP_CLOCK || NET_L2_PTP
	help
	  Enable MCUX PTP clock support.

	help
	  Set the frequency in Hz sourced to the PTP timer.
	  If the value is set properly, the timer will be accurate.

config ETH_MCUX_PTP_CLOCK_INIT_PRIO
	int
	default 85
	help
	  MCUX PTP Clock initialization priority level. There is
	  a dependency from the network stack that this device
	  initializes before network stack (NET_INIT_PRIO).
